8 Claims. (til. 101-477) This invention relates to new and useful improvements in rotary type holders for mounting on the shaft of a machine, and is for a holder that provides a quick and easy interchange of type.

Rotary type holders of the type to which the present invention relates are extensively used in industry, commonly, but not necessarily, being used in complementary pairs between which objects, as for example can lids, are passed, and a code or other mark impressed therein. The nature of their use requires that fromv time to time the marking dies be changed to imprint a different marking. It has heretofore been the general practice to employ a holder that must be removed from the shaft of the machine in which the holder is used, after which screws or other fasteners must be removed from the parts, and the parts separated to remove the type, and all or part of the type replaced with new type. The various parts are then reassembled, the screws or fasteners replaced, and the entire assembly remounted on the shaft of a machine. This requires considerable time, and it is awkward to handlethe numerous parts of the holder and type at the same time.

My invention provides a rotary type holder applicable to existing machines, which need not, but may be removed from the shaft of a machine to change or rearrange type, and which is of simple, rugged construction. It further provides a locking member which is movable arcuately a few degrees to permit quick and easy removal and insertion of new type. After type is placed in the holder, the locking member is moved arcuately back to locking position and secured by a lock pin. The operation may be accomplished quickly and with a saving of time, and the manufacture thereof is simplified.

The principal object of this invention is to provide a type holder that permits quick and easy interchange of type.

Another object of this invention is to provide a holder that can be easily removed from the shaft of a machine, and which is of unique and simple construction and may be interchanged with existing holders and types.

This invention is an improvement in rotary type holders of the type disclosed in Weber Patent No. 2,358,674, of September 19, 1944.

Other objects and features of the invention will become apparent to those skilledin the art as the disclosure is made in the following detailed description of a preferred embodiment of the invention as illustrated in the accompanying sheet of drawing, in which:

FIG. 1 shows a plan view, partly in section, of a preferred embodiment of the invent-ion;

FIG. 2 illustrates a front elevation of the device mounted on the shaft of a machine;

FIG. 3 shows a side elevation of the device shown in FIG. 2; and

FIG. 4 shows a section of the device taken along the line IVIV of'FIG. 3.

Referring now -ot the drawing, wherein like reference characters designate like or corresponding parts throughout the several views, there is shown in FIG. 3 a rotary quick change type holder designated generally as mounted on a shaft 12 of a machine. The rotary quick change type holder 10 abuts a collar 14 formed on the shaft 12 and is secured thereto by locating keys 18 3,100,442 Patented Aug. 13, 1963 2 snapping into an annular groove 16 provided in the shaft 12. spring 20.

The rotary quick change type holder 10 as here shown comprises a second line type holder disc 22, a locking ring 24, a first line type holder disc 26, an end ring 28, and an end member or end plate 30, all arranged in faceto-face relation and held together by screws 32 passing through holes, provided in end plate 30, end ring 28, first line type holder disc 26 and threaded into type holder disc 22. The end ring 28 has a reduced portion 28' having non-circular holes broached therethrough to receive the keys i8, and the spring 20 encircles this hub portion. The locking ring 24 is an incomplete or segmented annulus, having a gap between its two ends, as clearly shown in FIG. 4.

To assemble the rotary quick change type holder, the

second line type holder disc 22 may be first slid onto the shaft 112, one end abutting the collar 14 formed on the shaft and limiting movement of the type holder in one direction. Locking ring 24 is then placed in abutting relationship to the type holder disc 22. Type holder disc 22 has a segmented notch or opening 23 in its circumference for receiving type 34 and an annular groove 36 on one face for receiving the raised portion or bead 33 provided on the face of the locking ring 24. The first line type holder disc 26, which also has a segmented notch 27 or opening for receiving type 34, is then placed on the shaft 12 in abutting relationship with looking ring 24. The inside diameter of the locking ring 24 moves arcuately on an annular shoulder 26 provided on one end of the first line type holder disc 26 (see FIG. 4). The first line type holder disc 26 also has a groove 40 provided on one face for receiving the annular raised portion or head 42 provided on one face of the end ring 28. When the parts are all assembled on the shaft, screws 32 are inserted to hold the parts assembled. A key 13 is shown for keying the holder to the shaft -12.

'For releasably holding the ring 24 against relative rotation in the assembly, there is a locking pin 44 passing through type holder disc 26 having its inner end projected into an opening in the ring 24. The pin passes through a sleeve 45 pressfitted into a recess in the outer face of the ring 28. A spring 44' urges the pin outwardly, while a transverse pin 45' passing through pin 44 engages the inner end of the bushing to restrain such outward movement. The inner end of the bushing is notched so that if pin 44 is rotated to the proper position, transverse pin 45 registers with the notches, allowing pin 44 to spring outwardly enough for its inner end to clear the ring 24.

When it is desired to change type, spring lock pin 44 is first retracted. This permits locking ring 24 to be rotated in a clockwise manner from a locked-in position as viewed in FIG. 4. The segmented opening in locking ring 24 will thus be aligned with the segmented opening in type holder disc 22 and the segmented opening in first line type holder disc 26. There is a stop pin 46 on that face of holder disc 22 which confronts the locking ring to limit the rotation of the locking ring by contacting an end of the locking ring to thereby prevent the ring from being turned too far. When the segmented openings are thus aligned, enough clearance space is provided to move the type 34 in both holders free from engagement of the type notches with the beads 38 and 42 for radially removing or changing the type or for rearranging it within the holders. After the rearranged or different type is inserted in the segmented openings of the type holders, locking ring 24 need be merely turned counterclockwise a few degrees and the type is locked in place. When the ring has been rotated to the full limit of its movement in the reverse direction and the The keys 18 are urged radially inward by a locking other end abuts pin 46, the lock pin 44 is pushed in and turned to prevent relative movement of the ring. As is usual in devices of this kind, the printing dies or type elements are notched on one side inwardly from the'outer end so that the bead 38 on the locking ring 24 enters the.

grooves or notches in the type in holder disc 22, and bead 42 of the holder disc 26 engages the type in such holder. The locking ring 24 prohibits axial movement of the type when rotated to the position shown in FIG. 4, and this locks the type against radial movement because the beads 38 and 4 2 are captured within the groovesof the type. The type elements are wedge-shaped, and their narrow inner ends bear on the shaft 12.

The entire assembly is held together by screws 3'2 pass- 7 ing through holes in end plate 30, end ring 28, first line type holder disc 26, and screwed into type holder disc 22. The first line type holder disc 26 is a discontinuous annulus or circular member of greater extent than 180, but less than 360, and the space 27 between the open ends of the ring-like member provide the type holding space. The locking ring 24 is a similar but thinner incomplete ring, and the space between its ends is of the same angular extent as the space between the ends of the type holder disc 26, so that when type is to be removed or replaced, the segmentaltareas between the open ends of these two members are in register.

If it is desired to remove the rotary quick change type holder from the shaft of a machine, a flat key of substantially the same width as the shaft diameter is inserted in a slot transverse the end of shaft 12 to spread the locating keys out of the annular groove in the shaft, thus permitting the removal of the type holder assembly.

. Because of the non-ciroular holes in the hub portion of the end member 30 which have the locating keys i8 slidably fitted therein, these keys being also non-circular where they pass through the holes so that they cannot rotate, the ring-like spring 20 is all that is required to retain them in place. A

It should be understood, of course, that the foregoing disclosure illustrates a preferred embodiment of the invention and that various modifications or alterations may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims.
